The Microsoft Kinect v2 sensor can provide skeleton data for a user in real-time, however, due to occlusion issues and front/back ambiguity errors, one Kinect is not always reliable enough for the correct capture of 360-degree movements. In this paper, we present work to provide robust, real-time tracking using multiple Kinect v2 cameras. An adaptive data fusion method is described that constructs a high-quality 3D skeleton which can be used to drive a VR avatar regardless of the user's orientation. We compare three different approaches to fusing the data from the three Kinects, and compare against ground truth using an OptiTrack system. A static pose and a dynamic movement were captured to compare errors of each joint using the three fusion algorithms. Our results show that an adaptive weighting adjustment fusion method for combining skeleton data from the three Kinects according to the current facing direction performed best in terms of joint error.","PeriodicalId":264923,"journal":{"name":"2018 10th International Conference on Virtual Worlds and Games for Serious Applications (VS-Games)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114035066","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In psychotherapy, VR has been identified also as a promising treatment instrument. This paper presents a study on VR assisted psychotherapy, evaluating the effects of graphical styles on emotional states of N=74 subjects. Assessed data has been used to first statistically check, if the presented VR-scenes can create a positive emotional effect, here relaxation. In addition, we examined the difference of changes of the emotional state with respect to two different graphical styles, both being typical for state-of-the-art video games. One of these styles is supposed to render highly realistic scenes at high computational costs. The second style has been deliberately chosen, to present an alternative requiring low performance devices such as mobile phones on wireless VR devices. As a third research target, we surveyed the difference of measured effects with respect to technical background knowledge of subjects. The study has been set up as a pre-study acquiring healthy students as subjects instead of patients suffering from psychological disorders.","PeriodicalId":264923,"journal":{"name":"2018 10th International Conference on Virtual Worlds and Games for Serious Applications (VS-Games)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115476940","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents the learnings and challenges for designing such a game from a research through design perspective. Central in this paper is the process employed to design the ReadySetGoals, a gamified mobile application aimed at supporting therapeutic goal setting within a substance addiction treatment context. The design process involved four key stages. 1) The 'transfer effect' was identified and then 2) The 'Real World' context examined. 3) Different gamification concepts were evaluated and a 'core gamification loop' was designed. 4)The ReadySetGoals was then prototyped, user tested and iteratively refined. During the design process, three key learnings emerged and are discussed: 1) Aligning stakeholder expectations though framing 2)Integrating real world therapeutic aspects in a game world experience and 3) The value of personalization.","PeriodicalId":264923,"journal":{"name":"2018 10th International Conference on Virtual Worlds and Games for Serious Applications (VS-Games)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131355596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
